MIT400/2 CAT IV Insulation testers

MIT400/2 CAT IV Insulation testers MIT400/2 CAT IV Insulation testers Designed for Electrical and Industrial testing Insulation testing up to 1000 V and 200 GΩ range Stabilised insulation test voltage (New) Single range, faster continuity testing from 0.01 Ω to 1 MΩ (New) Adjustable insulation test voltage from 10 V to 1000 V (New) 600 V Trms AC and DC voltage measurement Test result storage and Bluetooth downloading Live circuit detection and protection Rechargeable options for mains and car charging (New) CAT IV 600 V and IP54 DESCRIPTION The MIT400 mk2 series insulation and continuity testers are designed not just for Electrical and Industrial, but with an exceptionally wide range of applications from electrical installations, cable testing, motor testing, automotive, ESD, panel building, avionics, maintenance etc. Insulation testing has been enhanced with feedback controlled test voltages to limit over-voltage to 2%, rather than the industry standard 10-20%. A variable range has been added to allow any intermediate voltage from 10 V to 1000 V in 1 V steps, where application specific test voltages are required that do not appear in the standard ranges. Continuity testing is now significantly faster, and a single autoranging 0.01 Ω to 1.0 MΩ function replaces the ohms and kohms ranges. Retained are the 200 ma and 20 ma test options. THE MIT400 RANGE: The range consists of four instruments: MIT400/2 250 V, 500 V and 1000 V MIT410/2 50 V, 100 V, 250 V, 500 V and 1000 V + PI, DAR MIT420/2 50 V, 100 V, 250 V, 500 V and 1000 V + PI, DAR + VAR (New) and result storage MIT430/2 50 V, 100 V, 250 V, 500 V and 1000 V + PI + DAR + VAR (New) + Bluetooth download INSULATION RESISTANCE TESTING: The stabilised insulation test voltage is now accurate to +2% -0%. This compares to the industry standard +20%, providing a more accurate test voltage without the risk of over-voltage damage to circuits or components. The output voltage is maintained between 0 and 2% throughout the test range. Replacing the original MIT400 instruments the new units feature a redesigned case, back-stand, and 6 cell battery compartment with separate fuse access. Where a non-standard test voltage is required, a variable range allows the exact test voltage to be selected from 10 V up to 1000 V. and is subject to the same stabilised output control. All instruments are over-moulded for increased protection and achieve an IP54 weatherproof rating.

FEATURES INCLUDE: Test voltages (New) * - 50 V, 100 V, 250 V, 500 V and 1000 V. Variable test voltage (New) * - Adjustable test voltage from 10 V to 1000 V. 2% test voltage accuracy - The output test voltage is maintained within the tolerance or -0% +2% PASS/FAIL indication (New) * PASS or FAIL displayed depending on threshold voltage Stabilised test voltage - The voltage is feedback controlled to ensure it remains within specification throughout the full test range Test voltage display (New) - The actual test voltage is displayed on the smaller digital readout, with the measurement on the larger digital display. Measurement range displayed (New) * - The test range is displayed during selection Measurement voltage display - The measurement voltage is displayed during the test Analogue arc - The display also features an analogue arc to replicate the response of a moving coil display. PI and DAR * - Polarisation Index (PI) and Dielectric Absorption Ratio (DAR) functions - Polarisation Index (PI): 10 min / 1 minute ratio - Dielectric Absorption Ratio (DAR ): 60 sec / 30 sec ratio Timed testing * - Automatically test to a time limit High test range - Insulation testing up to 200 GΩ at 1000 V. Silicon leads - High quality flexible silicon test leads are comfortable to use and prevent measurement errors on GΩ ranges above 5 GΩ. Test inhibit - prevents testing if voltages in excess of 25 V, 30 V, 50 V, 75 V 100 V (set by the user) are detected when making insulation tests. (Default is 50 V.) Insulation buzzer - The buzzer can be set to buzz if the insulation resistance is above a user adjustable limit, set in the Setup menu. Test Lock - Holds insulation test on continuously. CONTINUITY (RESISTANCE) TESTING: Single resistance range (New) - One range fully automatic from 0.01 Ω to 1.0 MΩ. Bi-directional testing (New) * - Option for automatic bi-directional testing without reconnecting leads. 200 ma or 20 ma * - Either 200 ma or 20 ma continuity test currents are available. 20 ma test current will considerably increase battery life. Lead null - Lead resistance compensation (NULL) operates up to 10 Ω of resistance. Buzzer - ON/OFF selected by simple push button. Buzzer limit - Continuity buzzer limit alarm provides adjustment of the maximum resistance the continuity buzzer sounds. This is adjustable from 1 Ω to 200 Ω in 12 steps. VOLTAGE MEASUREMENT: True RMS voltage measurement to 600 V ac or dc with resolution from 0.1 mv. Digital voltage measurement up to 600 V ac/dc Analogue arc measurement to 600 V ac/dc Automatic display of frequency during voltage measurement.

OTHER FUNCTIONS AND FEATURES Weatherproof - Every tester is sealed to IP54, providing a weatherproof case to reduce the chances of water ingress, including the battery and fuse compartment. Tough housing - Rubber over moulding combines the tough shock absorbing outer protection with excellent grip, on a strong modified ABS housing, providing an almost indestructible case. Batteries - Battery requirements are 6 AA batteries of either standard Alkaline or Nickel Metal Hydride (NiMH) rechargeable type, providing a minimum of 3000 insulation tests at 1000 V.

The test results are downloaded to a CSV file which can then be opened as an Excel spreadsheet. SAFETY Designed to be exceptionally safe to use, fast detecting circuitry prevents damage to the instruments if accidentally connected to live circuits or across phases. Specifically, all instruments: Meet the international requirements of IEC61010 and EN61557. Live circuit detection inhibits insulation testing on circuits above 25 V, 30 V, 50 V, 75 V or 100 V (default 50 V). Live circuit detection and test inhibit on continuity measurements. Default display of live circuit voltage on all ranges. Detection and inhibit functions even if the protection fuse has failed. Suitable for use on CAT IV applications and supply voltages to 600 V. 3
